A newspaper article has the headline "Google says it's actually quite small" According to the article:

Google rejects the idea that it's in the search advertising business, an industry in which it holds more than a 70 percent share of revenue. Instead the company says its competition is all advertising, a category broad enough to include newspaper, radio and highway billboard.

Why does google care weather people think it is large or small? Do highway billboards actually provide competition for Google. Briefly explain. Please state wheather the actual demand were a)to the right or to the left the where the company thought it would be and b) flatter or steeper than the company thought they would be.
